Sorry, you've asked this a few times and I've been meaning to answer.

TL;DR: No, I ended up at Fedora and am very happy with a few caveats

Bazzite's concept of an 'immutable' system based on Fedora Atomic Desktop may be good to keep Linux newcomers from accidentally damaging their system, but for someone using Linux since the turn of the century that just gets in the way.

Bazzite is known for improved and streamlined Nvidia support, which does nothing for me on this all-AMD rig.  It's also primarily aimed at being primarily a games system and secondarily anything else; I can and have installed Steam under Fedora, but to me that's Just Another Repository rather than the OS's main reason for existing. Games that work on the Steamdeck Just Work on Fedora too.

The final straw was the slow boot time. Really slow. Between two and four minutes. Asking in the Bazzite forums (not Discord or Reddit or Git, but yet another NIH forum system) got back a canned answer (but not a solution) because the problem is so common.

I started looking at the forums and it seemed clear that there was lots of diagnosis going on without any clear solutions on offer. There clearly isn't a coherent grasp of the problem even though it appears to be quite common.

I admit to lacking patience, especially with a distro that touts itself as being super newbie friendly. I decided to go with Fedora as a safer, better understood path. No snaps and no software designed to lay blame. Haven't looked back for a moment.

PS: The move to Fedora was impressively smooth, and my culture shock after being in Ubuntu (and Ubuntu-based) land for decades was minimal. Going from apt to dnf involved minimal fuss. My remaining challenges on Fedora are mainly power management. Sometimes USB devices won't work when waking from sleep and sometimes the whole system refuses to wake after sleeps and needs to be power-cycled. "Screen off but don't sleep" doesn't seem to work either. Any help on this issue is appreciated.
